Vercel's agent-browser: Why a CLI Beats MCP for Browser Automation
Vercel's agent-browser hit 22,000 GitHub stars in two months. It's a CLI, not an MCP server, and the data shows why: 94% fewer tokens, 3.5x faster execution, 100% success rate. We break down how it works, why it uses the accessibility tree, and what the 'less is more' finding means for your website.
Playwright: From Test Runner to AI Agent Interface
Playwright overtook Cypress, then Microsoft shipped Playwright MCP — turning the same tool into the standard browser runtime for AI agents. We break down why the data-testid vs getByRole debate now determines whether agents can use your site, the testing-accessibility-agent flywheel, and what this means for frontend teams.
How AI Agents See Your Website: The Accessibility Tree Explained
AI agents don't see your website the way humans do. They navigate via the accessibility tree — a browser-generated structure originally built for screen readers. We explain how it works, which AI frameworks use it, and why accessible websites outperform in the age of AI agents.
What Is agents.json? Advertising AI Agent Capabilities on Your Website
agents.json is the emerging complement to robots.txt - a machine-readable file that tells AI agents what your website can do. We cover the Wildcard specification, compare it to A2A, MCP, and OpenAPI, and show you how to implement it step by step.
What Is MCP? The Model Context Protocol for AI Agents
Anthropic's Model Context Protocol (MCP) connects AI assistants to external tools and data. We cover the architecture, discovery via /.well-known/mcp.json, current adoption, and how to implement it.
What Is Google's A2A Protocol? Agent-to-Agent Communication Explained
Google's Agent-to-Agent (A2A) protocol lets AI agents discover and work with each other. We cover the Agent Card, task lifecycle, A2A vs MCP, the partner ecosystem, and step-by-step implementation.
What Is WebMCP and Why Your Website Needs It
WebMCP is the W3C proposal for exposing website functionality directly to AI agents. We cover the Declarative and Imperative APIs, site-wide discovery, browser support timeline, and step-by-step implementation with code examples.
What Is AI Agent Readiness and Why Your Website Needs It
AI agents are changing how the web works. Learn what AI agent readiness means, why it matters for your website, and how to prepare for a world where autonomous agents browse, parse, and interact with your content.
